What are the different types of exotropias

1. congenital/infantile exotropia
2. intermittent exotropia
3. divergence excess
4. basic exotropia
5. convergence insufficiency
6. decompensated exotropia
7. consecutive exotropia
8. sensory exotropia

2

Exotropias are more frequent in _____, asian, and AA, and more common in regions closer to the equator. ______ is rare due to intermittency. _____ and ____ patterns are common which is seen in OIO and OSO. Neurologic etiologies are common in infantile exotropia and adult onset exotropia.

females; amblyopia; A; V

3

What happens when you have OIO in exotropia

A pattern: exotropia greater on down gaze
V pattern: exotropia greater in upgaze

4

Congenital/infantile exotropia is rare unless craniofacial/neurologic problems exist. Age of onset is

1; 80; -3.50

5

What are motor anomolies of congenital exotropia

1. limited adduction on versions, not ductions
2. DVD (dissociated vertical deviations)
3. overaction of inferior or superior obliques (A, V, or X pattern)

6

In order to treat congenital/infantile exotropia you need to rule out _____ etiology first! Then correct for RE, treat any amblyopia, consider surgery weighing neurologic fragility (prior to 10 months if possible) - lateral rectus recession is performed. It has a poor prognosis for normal binocular vision
